Photography


Photography is a art, application, & practice of making durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive the tangible substance that goes into the makeup of a physical thing such as photographic film. it is for employed in many fields of science, manufacturing e.g., photolithography, as well as business, as alive as its more direct uses for art, film together with video production, recreational purposes, hobby, and mass communication.

Typically, a lens is used to focus the light reflected or emitted from objects into a real notion on the light-sensitive surface inside a camera during a timed exposure. With an electronic abstraction sensor, this produces an electrical charge at regarded and identified separately. pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The total with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the goal of the photographic material and the method of processing. A negative image on film is traditionally used to photographically pretend a positive image on a paper base, required as a print, either by using an enlarger or by contact printing.

Etymology


The word "photography" was created from the Greek roots φωτός phōtós, genitive of φῶς phōs, "light" and γραφή graphé "representation by means of lines" or "drawing", together meaning "drawing with light".

Several people may make coined the same new term from these roots independently. Hercules Florence, a French painter and inventor well in Campinas, Brazil, used the French form of the word, photographie, in private notes which a Brazilian historian believes were a thing that is said in 1834. This claim is widely featured but is not yet largely recognized internationally. The first use of the word by the Franco-Brazilian inventor became widely requested after the research of Boris Kossoy in 1980.

The German newspaper Vossische Zeitung of 25 February 1839 contained an article entitled Photographie, examine several priority claims – especially Henry Fox Talbot's – regarding Daguerre's claim of invention. The article is the earliest known occurrence of the word in public print. It was signed "J.M.", believed to have been Berlin astronomer Johann von Maedler. The astronomer Sir John Herschel is also credited with coining the word, self-employed person of Talbot, in 1839.

The inventors Nicéphore Niépce, Henry Fox Talbot and Louis Daguerre seem non to have known or used the word "photography", but returned to their processes as "Heliography" Niépce, "Photogenic Drawing"/"Talbotype"/"Calotype" Talbot and "Daguerreotype" Daguerre.
